2003 aztek electrical problems

[aomens75]

Hi I have 2003 aztek and when I drive it if the blower motor is on at all it blows a fuse, security light comes on and it locks the key in the ignition. most of the time I just replace the fuse get the key out and be on my way but there has been times when I had to get towed. any suggestions would be appreciated. thank you.

You have a short in the circuit to the blower motor. it could be the switch, the relay, the resistor or the motor.
